How To Tell Difference Between Gyno And Breast Cancer

Easy:
Gynecomastia, right? You probably want it removed surgically; the pathologist will take a look at it and you'll know for sure. Symmetric enlargement under a man's nipples is almost always gynecomastia; if it ulcerates or keep growing or is invading, then it's time for biopsy or wide excision.

Breast cancer results when glandular cells lining the milk ducts and lobules of the human breast begin to grow in an unregulated manner. The growth occurs initially inside the ducts but eventually breaks outside into the breast tissue and ultimately spreads both to the lymph nodes in the armpit and via the bloodstream to other parts of the body. Because of the promoting affect of estrogen almost all breast cancer occurs in women and is a rarity in men. The unregulated growth is due to both inherited and acquired genetic defects. It is the most common malignancy in women but it often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast on an annual basis.

Definitions:
A tumor is a general term for a lump or mass in any location in the body. It can be cancerous or noncancerous. Breast cancer refers to malignant cells found in the breast. There are many benign/noncancerous tumors that can be found in the breast. Usually a needle biopsy is performed to determin if cancer is present.

T Stages:
I think you are talking about primary tumor stage (eg t stage). T4a is a breast tumor that has grown into the chest wall, t4b is one that basically invokves the skin, t4c involves both chest wall and skin, and t4d is inflammatory carcinoma where the entire breast is red and swollen due to extensive cancer. These are combined with the nodal (n) and metastasis (m) stages to give overall stage.

See your doc:
There are subtle differences, but a good rule is that paget's should be excluded for any persistent rash in the nipple area. If the patient has known eczema in other parts of the body, she will usually recognize it as such. Eczema rarely starts out in the nipple area only.

Cancer v. Node:
Lymph node is a structure in the body that screens lymph that is being drained from surrounding tissue against infection. Breast cancer is a collection of cells from breast ducts/lobules (usually) that have become immortal and often rapidly proliferative whereby they invade surrounding tissues depriving normal cells the ability to co-exist. Cancer cells may find their way to nearby lymph nodes.

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing repair of DNA damage.
